NATURAL DIAMONDS – certified GIA, IGL, EGL, or DGI. Stones are guaranteed and certified.

MOISSANITE- professionally certified. They are made of silicon carbide, which is the same material that makes up natural diamonds. They are very durable and resistant to scratching and chipping with Mohs hardness of 9.25, which is just below that of natural diamonds (10). Our moissanite is more brilliant than natural diamond at a fraction of the cost. We only use the best of the best! D-F/VVS1 Clarity. Our primary moissanite is available in clear, black, yellow, green, and grey. While we also offer other colored moissanite, note that these are coated and may fade over time. However, every one of them will pass the diamond test. Black Diamonds- New York Moissanite is among the hardest minerals on earth, more durable than sapphire, ruby, or emerald. 

PREMIUM CVD DIAMONDS (Chemical Vapor Deposition Diamonds)- These are lab-grown and atomically identical to mined diamonds and are composed of pure crystalline carbon. Our CVD process for these stones relies on a unique and innovative process that makes them look exactly like so-called “natural” diamonds. In fact, even a trained jeweler cannot identify the difference. Our Premium CVD Diamonds will pass the diamond test and can only be made available for stone upgrades at a premium cost. 

HPHT DIAMONDS (High Pressure High Temperature Diamonds)- These are lab-grown diamonds that are created using the high-pressure, high-temperature (HPHT) method. This method involves subjecting a small diamond seed to extreme heat and pressure, which causes the carbon atoms in the seed to bond together and form a larger diamond. HPHT diamonds are typically yellow or brown in color, although they can also be colorless or near-colorless. HPHT diamonds are typically more expensive than other types of lab-grown diamonds, such as CVD diamonds. This is because the HPHT process is more energy-intensive and requires more specialized equipment. However, HPHT diamonds are also considered to be more durable than other types of lab-grown diamonds.

DIAMOND ALTERNATIVE

EVN STONES- This is the newest masterpiece of our lab using the same process as our CVD Diamonds. They are not natural diamonds but they look like one– brighter, shinier, and even more mesmerizing than any stone we laid our eyes upon. Superiorly cleaner and flawless than any stone. EVN stones are without a doubt an excellent alternative to real diamonds.

SONA SIMULATED DIAMONDS- Not mined diamonds but sparkle like one. It is difficult to distinguish the two with the naked eyes. Each stone is cut to maximize the radiance with the intent to create a collectible custom piece. Polished with natural diamond polishing wheels- the exact process to polish high-quality natural stones. Expert diamond cutters guarantee that our Sona Simulated Diamonds are a cut above the rest. Premium stone with excellent cut, no one would know you did not spend a fortune. 

CREATED DIAMONDS - Not natural earthed diamonds but these are very expensive stones. The stones are made from zirconium dioxide that boast fine colour, no colour mixing, and a superb cut, which result in a beautiful duplication of nature. 

NATURAL GEMSTONES - We offer natural gemstones including amethyst, citrine, garnet, ruby, sapphire, emerald, morganite, peridot, topaz, aquamarine rose quartz, and tourmaline. Plus many more.

ARE THESE REAL DIAMONDS AND WILL PASS THE DIAMOND TEST?
All our Natural Diamonds, Premium CVD Diamonds, HPHT Diamonds, and Moissanite Diamonds will pass the diamond test. Our EVN Stones, Sona Simulated Diamonds, and Created Diamonds are lab-grown diamond imitators and will not pass the test. However, these are the BEST alternatives to natural diamonds. They look just the same, but they cost much less. At about only 1% of the cost of a diamond, you can take a stone that is equally beautiful and shining. Check our stone authenticity for more info.

DIAMOND CERTIFICATE
All our Natural Diamonds with 0.40 carat and up will come with a GIA certificate and GRA certificate for all our Moissanite with .50 carat and up. Certificates for all custom-cut moissanite and natural diamonds are only available upon request.

FREE BLACK PLATING MAINTENANCE
Black rhodium silver or gold is dark grey to black in color plating. Black plating is a very intricate process and varies each time. Plating longevity is very dependent on the individual and the environmental conditions it is exposed to, water, soaps, natural skin oils, chemicals etc. Black rhodium is a temporary finish only, we have seen plating last anywhere from days, months to even years. This depends on how well it's looked after and also the natural oils in our skin. Black rhodium can be redone at any time.
